The Architecture of Trees is a botanical masterpiece. It features over 550 pen-and-ink illustrations of 212 tree species, with and without foliage, at a 1:100 scale. Furthermore, it presents a study of shadows and colors that provides a new perspective on each species. This historical study, now available in Spanish, is a reference for architects, designers, botanists, and all those fascinated by nature and trees. Edited by Andrea Cavani and Giulio Orsini, founders of the Cesare Leonardi Architectural Archive, this book illustrates the birth, development, and advancements in the tree research of Cesare Leonardi and Franca Stagi.
